EDI-IN MGLAUGHLIN, 0F JERSEY CITY, NEW JERSEY, ASSIGN OR*T'U UNDERWQOH TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CORPORATIQN OF DELAWARE.

TYEE-WRITING- MACHINE.

To all whom it may concern: Be it known that I, J HN C. Mel/Anon- LIN, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful'lmprovements in Typeu Writing Machines, of which the following is a specification.

This invention relates to tabulating mechanisms for typewriting machines, wherein usually a carriage movable upon a frame, has one or more column stops to contact with key-operated stops on the frame, to arrest the carriage at different points in the printing line, corresponding with'the printing.

. positions of the first characters in difi'erent columns, the carriage being jumped from the printing point of thelast character in one column to the printing point of the first character in the next column.

'One of the objects of this invention is to enable the column stops to be quickly and easily shifted by an operator, to accordwith different columnar arrangements of forms or blank sheets, no special skill being required to adjust the mechanism or the stops;

' To this end, several rack bars, each having stops arranged thereon, are shiftably mounted on the carriage, so as to be severally brought into efiective position relatively to the key-controlled stops.

Another. object is to simplify and improve the mechanism whereby the column stops are releasably secured to the rack on which they are adjustably mounted, which I accomplish by providing each rack with a rotatable key ,toreleasably lock the stops against removal from the rack by entering recesses formed in. the stops. Y

In the accompanying drawings, Figural .is a perspective view of the invention, broken away and in section. Fig. 2 is a rear view, showing its relation to the keyrontrolled stops. Fig. 3 is an end view of the invention, partly in section, applied to an Underwood writing machine. Fig. at is a detail side view of a column stop. 'Fi

opposite end of the rack support from that shown in Fig. 3.

A carriage 1 is mounted for movement back and fortl' along the rail 1 of the frame 2 of an Underwood writing machine,

and is drawn iii-one direction by a spring 3,

the carriage having a rack 25 in mesh with .at P, and which projects a stop 5 carried by a plunger 5 (sliding in a guide casing 6), into the path of a column stop 7 on the carriage l, the operation of the key also effecting the release of the carriage from the usual letter-space mechanism-to allow the carriage to move freely across the frame,

under the influence of the spring 3 until the stop 7 (mounted on a rack 8 connected with the carriage) contacts with the key-coir trolled stop 5 to arrest the carriage. The release of the carriage is efiected through an arm 30 carriedby a shaft 31 mounted on the casing 6, and shifted'by a shoulder on any plunger 5. The plunger rocks the arm 30 to vibrate a second arm 33 on said shaft, said second arm being connected by a link 3% with one end of a releasing lever 35 pivoted at 36 to the frame 2. The opposite end'ofsaid lever contacts with the rack 25 to disengage the latter and hold it out of mesh with its pinion.

The rack 25 is restored to mesh with its pinion by a spring 29, and said stop- 5, plunger 5, key lever 43*, and key at, are returned to normal position by a spring 5*, the plunger being recessed at 5 to accommodate a bar 5 which limits the throw of the stop.

The stops 7 are forked to embrace the rack bar 8, being adjustably seated between teeth 11 thereof. They are held against acciden' tal displacement by a key rod .9, turning in a groove lO (Fig. 5), extending longitudh nally of and formed partly in the bar and partly in the teeth 11 thereof, the legs 1-2 of said stops being recessed, as at 13, to be com plementary to the groove.

The key rod 9 is cut away longitudinally to form a face 15, and by turning said rod axially, by its finger piece 14, the unreduced periphery of the bar enters the. recesses in the stops 7 on the bar to lock them in place. Further rotation .of the rod will bring the flat face l5thereof opposite the recesses 13 in the stops to enable the stops 7 to be withdrawn from the rack bar, (Fig. 7).

. Acollar 16 atone end of the locking key and a screw 17 at the opposite end, prevent endwise movement of the key 9 in the tabulating rack bar 8..

It will be noticed that the inner edges of both legs of the reversible stops 7 are recessed, so that the key may cooperate with either leg. i

To avoid the readjustment of the column stops 7 on the rack bar each time a different form is inserted in the 'machine, or whencvera different arrangement of columns is desired, and thereby to economize time and labor as well as to decrease the liability of error in adjusting the stops on the bar, I provide the carriage with several'tabulating bars 8, 8, 8", 8, each bar carrying a series of column stops 7 ,arranged therealong to correspond with a columnar arrangement different from the arrangements forwhich the column stops on the other bars are set. Said tabulating bars 8, 8, 8", 8, are fixed in heads 18, 18, fast ona shaft or pintle 19,

j ournaled in brackets 20 fastened to the'carriage 1.

Turning the-shaft or pintl'e 19 by a hand Wheel 21, (preferably having numerals, as shown in Fig. 2, designatin the respective tabulating bars 8, 8, 8*, 8 will revolve the tabulatingbars relatively to the keycontrolled stops until the desired bar is brought to operative position, avliere it is releasably locked by a spring finger 22,

which enters the recesses 23 in a locking disk nism of 'a typewriting machine, of a tabu lating rackbar, a bifurcated stop adjustably seated between any two ad acent teeth of the rack bar, said stop helng recessed, a rotatable locking rod connected to the rack bar and of greater diameter in one direction than in a direction transverse thereto to re leasably enter the, recess in said step to lock it against movementon the bar and a finger piece for rotating said rod.
